The app is cleverly disguised as "Audio Manager" in the App Drawer.Disguises itself as a Audio Manager app which can be used to turn the volumes up and down. but if you Long press on the Audio Manager title the actual Hide It Pro app will launch, which is basically your SECRET VAULT of pictures, videos, messages, apps etc.You can Hide photos, Hide Videos and Hide Media in your Private Vault

etc.There are a lot more features like custom slideshow durations/slideshow order/effects , custom folder thumbnails, Batch operations, Delete, Share, Unhide Move data between albums, Sort files and folders to your liking etc. but i'll leave some of the secrets of the app to be discovered by the users :)
